Hi Rob,

The line "use arq;" is there to tell psk_arq.pl to use stuff from the
arq.pm module (quite a lot of stuff actually). An error there probably
means that it was unable to find the module and its not installed
properly. That is a critical error, please recheck the installation.

Regarding the connects I wonder if you are able to ping the server?
Can you montor the server to see other stations connect?

I have worked pskmail from various places using only an FT-817 (5 watts)
and a random wire antenna (5 meters). For instance I used that from
Cyprus and connected to my server in Stockholm, had the antenna just
thrown over a tent then (a military tent hospital). That kind of
operation requires filters, I use real 500 Hz filters on both sides and
also noise reduction dsp on the server and narrow bandpass dsp on the
client radio now (I use an FT-897 nowadays).

If you have difficulties maintaining an arq connect then you could try
an aprs message or a pskaprs email message, those are async and could
get you started.
